251 registered, and how many unregistered? That, to me, qualifies as "around every corner" - not some rare boogie man, but I'll leave semantics alone.
I have volunteered helping the victims of these people. When you have heard the desperation of a woman crying at 3:00AM calling to talk to a stranger on a hotline because of the horror show her life has become, you tend to take a dim view of the perpetrators. Every single call, and they are numerous, sticks in your head forever. All because some subhuman wanted to get his rocks off and didn't care who he hurt.
We live in a society where you can get an order of magnitude more prison time for distributing weed than for raping children. If that's not a sympathetic public, I don't know what is.
